UNITED STATES WILLIAM H. LONG, OF NEW YORK, N. Y.

PRINTING PRESS.

Application filed February 26, 1919.. Serial No. 279,284;

To all whom it may concern:

Be it known that I, WILLIAM H. LONG, a citizen of the United States, anda resident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Print ing Presses,of which the following is a specification,

The invention relates to printing presses, and more especially toprinting presses adapted to either print in a plurality of colors, toperfect the impression receiving material, as may be desired, or toprint upon 'ones'ide of two webs, or other impression receivingmaterial, run through the press to ther.

he objects and advantages of the invention will be set forth hereinafterin part, and in part will be obvious herefrom, or may be learned bypractice with the invention; the same being attained through theinstrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts,

constructions, arrangements, combinations and improvements hereindescribed.

The accompanying drawings, herein referred to and constituting a parthereof, illustrate one embodiment of the invention, and together withthe descri tion serve to explain the principles thereo Of the drawings:'

Referring by way of example to the illustrated embodiment, a formcylinder 1 is provided, having inking mechanism, indiwhich mechanism inits details of construction may n acordance with certain features of theinvention,' the cylinder 1 is construct- .ed and adapted either forprinting directly.

'cated generally by the reference numeral 2, i

be of any acceptable or approved I upon a web,'or.-for printing upon anoff-set,

inder then printing upon the web.

In carrying out this feature of the invenor rubber-surfaced cylinder,this latter vcyl- I tion, there is provided a cooperating oifsetcylinder 3, and a cylinder 4. This latter cylinder in the arrangement ofthe press il-- lustrated in Fig. 1, operates as an' impression cylinder,but in the inter-relation of the cylinders shown in Figs. 2 and 3 it isadapted to operate as an off-set cylinderq'or asacombined off-set andimpression cylinder, receiving the impressions from the cylinder 1 andimparting them to the web as will be later described.

Means are provided for changing theposi- A tions and inter-relation ofthe cylinders 1, 3

and 4, for the purposes and objects described, and in the embodied formthereof the cylinder 1 and its inking mechanism 2 are mounted upon aframe 5 having base plates 6 and? which are slidable on guideways 8 and9 formed on' the press frame 10. On the base plates 6 and 7 at eitherside of the press, are formed gear racks 11 and 12, and meshing withthese gear rack bars, respectively, are pinions 13 and 14. Pinions 13and 14 are fixed upon a shaft 15 which is journalled at 16 and 17 in thepress frame. The shaft 15 is provided with a squared head or heads 18for the application of a crank.

In the embodied form of the invention, the cylinder 1 is adapted to useplanographic metal plates stretched upon the surface of the cylinder ina well-known manner. Suitable damping mechanism, which may be ofstandard or other convenient form, is provided for damping theplanographic printing plates preparatory to inking. By reason of thefact that in the present embodiment the direction of rotation of thecylinder 1 is'reversed, dependent upon whether it is in direct printingrelation with cylinder 3 or cylinder4, in my preferred embodiment, Iprovide two damping mechanisms,one such mechanism cooperating with thecylinder 1 while running in one direction, and the other dampingmechanism cooperating with the cylinder when it is rotating in theopposite direction, so that the damping operation .may in anyeventprecede the inking operation.

mechanism 23 is provided, mounted upon the frame IQ of the press, and inposition to cooperate w1th the press cylinder 1 when the cylinder 3 isinterposed as aprinting ele-,

ment or instrumentality between the cylinder 1 and the cylinder 4, asshown in Fig. 1. A second damping mechanism 24 is w mounted upon thepress frame, and is in po sition to cooperate with the cylinder 1 when;that cylinder is printing directly upon the it into operative relationwith elther the one damping mechanism or the other. 1

By" rotating shaft 15. cylinder 1 is slid along the press frame 10, tothe left-hand position as in Fig. 1 when cylinder 3 is interposed as oneof theprinting cylinders, and to the rlght-hand position as inFigs.

2 and 3, when cylinder 3 is out of operative position and cylinders 1and 4 cooperate directly.

In the embodied form thereof, a damping In the first of these twopositions, cylinder 1 moves into operative relation with damp ingmechanism 23 and in the second of these positions cylinder 1' moves intooperative relation with damping mechanism 24, as already described. v

In theembodied form of means for moving cylinder 3 into .and out ofoperative printing relation with cylinders 1 and 4, and as illustratedin Figs. 2, 4 and 5, cylinder 3 is elevated to what may be termedinoperative or non-printing position and is lowered into what may betermed the operative o1 printing ,.position. Referring in detail to theembodied means for so raising and lowering cylinder 3, the cylinder isjournaled at-either end thereof in a" journal block 25. Each of thejournal blocks is provided at either side with registering recesses 28and 29 which are in position to cooperate with registering pins 30 and31. This holds the cylinder firmly to position against the squeeze orpressure of the other cylinders.

The illustrated means for raisng and lowering the cylinder 3 comprisefurther lugs 32 fixed to or integral with the journal blocks 25 ateither side of the cylinder. Th'ese lugs are internally threaded, andvertically disposed screw rods 33 pass therethrough at either side ofthepress. The screw rods are journaled in top and bottom beari-n lugs 34and 35 on the machine frame at eit er side. Across the press frameextends a shaft 36, having at either end thereof a pinion 37, whichpinions mesh respectively with a diagonal or worm gearing 38 on-thebottom. end of each of the screw shafts 36. The shaft 36 has a squareend 39, whereby it may be rotated, to turn the screw shaft 31 andthereby to raise or lower the cylinder 3 from inoperative ornon-printing to operative or printing position and vice versa.

. 'Cooporating with the cylinder 4'isa cylinder '45, which is preferablyan off-set cylinder and cooperating with cylinder is a plate cylinder46, which is preferably a planographic cylinder, similar tocylinder 1.

Cylinder '46 is provided with an inking mechanism 47. and'with a dampingmechanism 48 both of, which may be of standard or other suitableform.The various cylinders are driven by gearing of suitable design,'butwhich is'not shown in the drawing; The manner of operation of thehereinbefore described mechanism. and the arrangements of the web orother impression receiving material for the various ways of print-- ingand interrelation of cylinders, is substantially as follows:

In Fig. 1a web 50 is shown in a roll at the left hand side, and isthreaded through the machine. passing between cylinders 3 and 4, andbetween cylinders '4 and 45, and

' out of the machine.

In the positions and inter-relations of the cylinders shown in Fig. 1,plate cylinder 1 rints upon off-set cylinder 3, which cylinder printsupon the web 50, the cylinder 4 acting merely as an impression cylinder.The plate cylinder 46 prints upon off-set cylinder. 45, which in turnprints upon the web 50, as it passes between the cylinder and thecylinder 4, the latter cylinder acting as an impression cylinder. Thisarrangement of the impression-receiving material and this interrelationon the cylinders provides for printing in two colors upon one side ofthe web.

*In Fig. 2 of the drawings, cylinder 3 has been moved to thenon-printing or inoperative position, and plate cylinder 1 has beenmoved into contact with cylinder 4, the impression-receiving materialbeing in the form of a web roll 51 and passing between the cylinder 4-and the cylinder 45. The plate cylinder 1 now prints upon the cylinder4, which latter cylinder operating as an off-set cylinderprints in turnupon the web 51. Plate cylinder 46 prints upon offset cylinder 45. inthe manner already described, and cylinder 45 in turn prints upon theopposite side of the web 51 from cylinder 4.- Cylinders 4 and 45 in thisarrangement act as off-set printing cylinders to print ,upon one sideof, and thereby to perfeet, the web, each cylinder at the same timeacting as the impression cylinder for the other.

In Fig. 3 of the drawings, two webs 52 and 53 of impression receivingmaterial are shown in roll form and as passing between the cylinders 4and 45, which cylinders operate in the same manner as last described.

reason of the two webs bein run together through the press, each web isprinted upon one side only, insteadof securing a perfected web as is thecase when a single web is run through, as shown in Fig. 2.

If desired, one of the two simultaneously the web 53 will'run through inthe manner shown in Fig. 3 and as already described,

' but the other web will run through in the same manner as the web 50,being printed upon by the plate cylinder 1, the cylinder 55 4 in thecase acting only as an impression cylinder, while the web 53 will beprinted by" the cylinder 45 in off-set as already described. Drivinggears for cylinders'l, 3.

and 4 are shown in Figs. 4 and 5, but are omitted from Figs. 1, 2 and 3for the sake of clearness. It will be understoodthat the drivingconnections for the press may'be of an usual and suitable character.

n Figs. 6 and .7 are shown a different form of mechanism for changingthe relation. of the cylinders 1; 3 and 4. In this form or embodiment ofthe mechanism, the

off-set cylinder 3 is moved downwardly,

pinions 59, which pinions are fixed on a shaft 60, the, shaft beingjournalled in the press frame. The shaft has squared heads to take acrank, the rotation of the shaft moving the cylinder 3 into and out ofprinting or operative relation with the plate cylinder 1 and impressioncylinder 4.' v

Means are provided in connection with the last-described mechanism forholding in position and for regulating or adjusting the position ofclinder 3. As embodied, on the bottom en of the slidable frame 56, ateither side thereof, are provided a stop and an interponent movableinto'and out of position, to support the cylinder either in its upper orprinting positionior in its lower on non-printing position. As shown,the movable stops comprise two arms 61, 'at either side of the slidingframe 56 and each pivoted thereto at 62. I v

The cooperating stop, which also provides in this embodimest theregulation or .ad-

justrnent for the printing pressure or squeeze, comprises a lug 63 onthepress frame, which is internally screw-threaded.

Threaded the'reinto is a .bolt 64, having locking nuts 65 and'66operating on either. side of lug 63. A corresponding device is on eachside of the press, and by turning the'bolts 64 at either side. thesqueeze or printing pressure of cylinder 3 is exactly determined oradjusted. I

By swinging arms 61 outwardly as shown in F ig'. 7, cylinder 3- may belowered by turning shaft 60 to the position shown in that figure, .andplate cylinder 1 moved up to print directly on'the web or to print oncylinder 4 as an offset cylinder. The remaining parts of the press maybe substantially as already described.
